Utilidad de la ecografía en dolor abdominal agudo de la fosa iliaca derecha, Hospital José Carrasco Arteaga Cuenca 2017

Abstract

Background: The pain of the right iliac fossa in the pediatric patient is not always caused by acute appendicitis; there are benign clinical entities up to surgical diseases, called "appendicitis simulators". Objective: To determine the usefulness of ultrasound in acute abdominal pain of the right iliac fossa, compared with the diagnosis at discharge, in pediatric patients of the José Carrasco Arteaga Hospital, Cuenca 2017. Methodology: his is a descriptive study and diagnostic test in pediatric patients with acute abdominal pain in the right iliac fossa, who underwent an abdominal ultrasound, from January to December 2017. The information was taken through a data collection form and statistical software for the descriptive study. Analysis using simple frequency and percentage tables. For the diagnostic test, sensitivity and specificity were obtained, positive and negative predictive value, positive and negative likelihood ratio. RESULTS: 301 patients were evaluated, 195 with pathology, 57.8% were between 10-15 years old, 50.5% are female. The following pathologies were observed; Mesenteric adenitis (33.6%), acute appendicitis (19.3%), gastroenteritis (5.6%), intestinal invasion (3.3%), hemorrhagic cyst and ovarian torsion (<2%). The ultrasound showed sensitivity 99.42, specificity 81.40. CONCLUSIONS: Abdominal ultrasound is an excellent tool to assess acute appendicitis and pathologies that mimic the pain of this disease. Although the sensitivity and specificity is varied in the literature, it should be the first modality of imaging in the pediatric patient.
